Subject [jira] [Commented] (MATH-1137) BOBYQA incorrect indexing
Date Thu, 17 Jul 2014 15:19:04 GMT


Gilles commented on MATH-1137:

bq. I did a few changes of initialisation of indices, Fortran set them to zero, I set them
to minus one, this may have an effect.

The effect of raising an exception (if the index is not set to a proper value before use),
you mean?

bq. I am now pretty confident my Java version works as it should

Anything that should be updated in our version?

bq. I still couldn't get the Fortran to exercise the lines which started all this (although
the Java does)

I don't understand; our current version does not exercise that section of the code.

bq. I have provided a further visual check of quite a lot of the code, so that can't be a
bad thing.

No, but how shall we keep a record of what is correct (and whose logic should be maintained),
what is probably not correct and what is undecided yet? If we leave it at that, CM users and
developers won't benefit from your review...
